UniTak3D Ender 3 V2 Y-axis Belt Tensioner Upgrade for Creality Ender 3 V2 Ender 3 Pro CR10 Mega Zero 2.0 Flashforge-Aquila AURORA-A5X 3D Printer 2040 Profile

Perfection took 3-5minutes for me to install and I’m a not an expert it 3 bolts to remove and install its thickness is just right reliability the amount of play or stretch u get is just right u get both ends of the spectrum loose to tight makes the sheerness of the line perfectly tont took the dip out of the middle I had on mine before upgrade my printer is a cr10s 400mm clone

A great choice for anyone who wants to replace the original Belt Stretch Straighten Tensioner on the Ender 3D printer.

Great fit and easy install on my CR10 Max. This tensioner is a must for all Creality 3d printers.

This has made getting the belt on my Ender 3 super easy and fast. For my ender 3 I did not have to re use any of the standard hardware which many people said they had to. I did not and I did not have to take the belt off to install this... I did have to take apart the entire part but it is straight forward and easy to understand.

This a solid unit already assembled ready to go! this took less than 10 minutes to install. Would have been faster but I took my time to get the correct tension with the knob. So easy ( Just 2 included hex screws NOT phillips yayy and 2 tension nuts) I am going right now to purchase 2 more for my other two Ender3 Pros. Thanks UniTak3D for a Great product and super fast Amazon shipping!

Easy to install on my Ender3, and it makes it much easier to maintain proper y-axis belt tension by allowing me to use the screw to tighten or loosen the belt. The entire replacement process took around 5 minutes and print results are just as good as before. Yes, you can print your own parts, but this one is made with metal so you dont have to worry about subjecting the part to too much tension. Affordable and easy upgrade to the stock y-axis belt tensioner.

This really helps keep the x axis belt tight. Has really improved my print quality.

Replaced a printed (PLA) tensioner on my CR-10 mini that came apart after a year or two of wear and tear. While I like printing mods in general, this is just more solid, easy to adjust and fits the rail and belt perfectly. The old printed mod was a little off and had some wiggle that led to some annoying belt rubbing from time to time.

This was necessary for my Ender 3 Pro; I was having stair-stepping issues after a whole year of printing and discovered that my X-axis cable kept jumping due to the slack it developed. However, after I installed this along with a fresh cable, the stair-stepping problem disappeared! I am fully aware that you can 3d print these, but metal lasts longer and it gives a more finished appearance; as if it were a part of the machine when I got it.

This is the second one that I have purchased. Work great and you can adjust on the fly. When installing you can take the item apart and install it without messing with the belts. Happy!!! Thanks
